NT Olympiad Fundamentals  

Instructor: Cordelia Hu

In this course, we cover many of the fundamental concepts in late-AIME and Olympiad number theory, such as divisibility, size bounding, modular arithmetic, polynomials, and orders. By taking this course, you'll gain a solid foundation on number theory at a high level.

Schedule

LESSON 1: Divisibility

LESSON 2: Modular Arithmetic

LESSON 3: Exponents and Orders

LESSON 4: Polynomials

LESSON 5: Miscellaneous

LESSON 6: Review and Test

Algebra and NT Fundamentals  

Instructor: Laura Zhang

This course will provide an introduction to early-AIME algebra and number theory. Students will learn how to tackle problems using techniques like Vieta's formulas, roots of unity, modular arithmetic, logarithm properties, and more.

Schedule

LESSON 1: Polynomials

LESSON 2: Divisibility and Bases

LESSON 3: Complex Numbers

LESSON 4: Modular Arithmetic

LESSON 5: Harder Equations and Inequalities

LESSON 6: Review and Test

Spicy Geometry  

Instructor: Serena Xu

In this course, we are going to talk about the five unique hearts of triangles and some famous theorems. Topics will include the special property of five centers and some interesting theorems, such as Ceva, Ptolemy, Monge and so on. In particular, we will solve some kinda-wonderful problems in each class!

Schedule

LESSON 1: Circumcenter and Incenter

LESSON 2: Centroid, Orthocenter and Excenter

LESSON 3: Menelaus and Ceva

LESSON 4: Ptolemy and Simson

LESSON 5: Power of a Point and Radical Axis

LESSON 6: Review and Group Solve

Algebra and Combinatorics Trail Mix  

Instructor: Nicole Shen

In this course, we will go over some common techniques used on mid AMC- to early AIME-level problems. Students will become familiar with methods and tricks that cover a variety of topics, especially in combinatorics and algebra. Topics include bijections, algebraic manipulation, using inequalities, sequences and series, and recursions.

Schedule

LESSON 1: Counting Clever Correspondences

LESSON 2: Algebraic Manipulation

LESSON 3: Inequalities

LESSON 4: ∑equences and ∑eries

LESSON 5: Recursion and States

LESSON 6: Look to the Future

Cute Geometry  

Instructor: Vivian Loh

This course covers all sorts of AIME-level topics related to triangles, plus a tiny peek into olympiad geo with cyclic quadrilaterals and cool orthocenter properties. Some topics included are area, Power of a Point, and trig bashing.

Schedule

LESSON 1: Similarity and Congruence

LESSON 2: Lengths and Areas

LESSON 3: Triangle Centers

LESSON 4: Circle Magic

LESSON 5: Trig

LESSON 6: Geometry Test!

Counting Strategies  

Instructor: Michelle Kang

This course is designed to help you enhance your combinatorics problem solving skills for early to mid AIME level problems. We will cover many different techniques, such as constructive and complementary counting, recursion, expected value, and bijections.

Schedule
